Currently, Kane is on a hiatus from the company to run for mayor in his hometown and will likely be gone from television until later this year. But it's being speculated that the "Big Red Monster's" current contract is set to expire next year and that this could be Kane's last contract as a active competitor.
Kane has been a part of the WWE since 1995 when he made his debut as Jerry Lawler's dentist and though that didn't really last too long the man real named Glen Jacobs made an impact because he would be back again once more next year as Fake Diesel before becoming the character that'd make him a legend. The Big Red Monster joins his "brother," Mark Henry, and Big Show as the last active wrestlers from the period of Attitude. There is no doubt that Kane will become a Hall of Famer eventually, but can you imagine Kane as mayor that sounds like a WWE storyline. Good luck to Kane as he earned some time off!
